This year’s Glastonbury Festival will see the debut not of a great new music act but at a cell phone battery charger that will work by human beings dancing.

Orange, a carrier out of England, is partnering with a renewable energy company called GotWind (which needs no punchline on our end) to produce a prototype which is worn on the arm and uses “a system of weights and magnets which provide an electric current to top up charge in a storage battery. This can then later be used to recharge the phone,” according to Reuters.

So don’t just stand there, bust a move! Do the Recharge, this summer’s crazy new dance! You may look like you’re doing the Flintstone Flop, but at least your phone will work. As if you’ll be able to hear it ringing at the Glastonbury Festival anyway.
